MRPL PP Mangpol HY035UR
MRPL PP Mangpol HY035UR is a controlled-rheology polypropylene homopolymer fibre grade manufactured by Mangalore Refinery and Petrochemicals Limited using solvent-free Novolen gas phase polymerization. Designed for non-woven, extrusion lamination, medical apparel, baby hygiene, packaging, and diaper applications, this high-flow PP grade is built for converters that need stable processing, clean fibre formation, and reliable end-product performance.
Mangpol HY035UR sits in MRPL’s fibre and non-woven grade basket alongside HY035R and is positioned for high-speed spunbond and related conversion lines. The grade is recognized as a 35 MFI polypropylene homopolymer with controlled rheology, making it suitable where smooth flow, consistent web formation, and dependable mechanical balance are critical. MRPL’s polypropylene portfolio is produced through Novolen gas phase technology with Ziegler-Natta catalyst systems, supporting low gel content, lot-to-lot consistency, and good organoleptic characteristics.
Technical Insights
MRPL HY035UR is understood as a fibre-grade PP homopolymer with a melt flow index of about 35 g/10 min at 230°C/2.16 kg. In the closely aligned HY035R class, typical performance values include tensile strength at yield around 33 MPa, tensile elongation at yield around 8%, flexural modulus around 1300 MPa, Izod impact strength around 28 J/m, and Vicat softening point near 152°C. This property profile gives processors a useful balance of flow, stiffness, and thermal resistance for lightweight non-woven structures and extrusion-lamination applications.
From a processing standpoint, the grade is suited to fibre spinning and non-woven conversion where stable melt behavior matters. Typical operating guidance includes barrel temperatures around 195–235°C, die heater temperatures around 235–240°C, and quench air temperatures around 15–18°C. The controlled-rheology profile helps support high-speed throughput, while low gel tendency reduces the risk of spinneret blockage and surface defects. A related product-family advantage is resistance to gas fading, which is valuable where appearance retention and shade stability matter in hygiene and medical non-woven products.
Applications
Non-Woven Spunbond
Mangpol HY035UR is highly suitable for spunbond non-woven production used in industrial and consumer applications. Its high-flow fibre-grade profile helps converters achieve stable filament formation, uniform web structure, and efficient processing on high-speed lines. This makes it a strong fit for non-woven manufacturers seeking polypropylene granules for consistent spunbond output in India.
Medical Apparels and Surgical Fabrics
This MRPL PP grade is well positioned for medical apparel applications such as gowns, drapes, mask layers, and other disposable healthcare fabrics. The combination of controlled rheology, process consistency, and clean conversion behavior supports manufacturers that require dependable non-woven performance for medical and hygiene-oriented production.
Baby Hygiene and Diaper Structures
HY035UR is also relevant for baby hygiene products including diaper components and related absorbent hygiene structures. Its flow behavior supports lightweight non-woven layers, while its mechanical balance helps maintain fabric integrity in demanding end uses. For diaper and hygiene converters, this makes the grade attractive where softness, processability, and production stability are all important.
Packaging and Extrusion Lamination
In packaging and extrusion lamination applications, Mangpol HY035UR offers the flow profile needed for efficient coating and lamination operations. It is suitable for converters looking for polypropylene homopolymer grades for laminated packaging structures where smooth processing, thermal stability, and reliable line performance are key selection factors.
Comparable Alternatives
Within MRPL’s own portfolio, HY035UR is clearly differentiated from low-MFI raffia and film grades such as HR003 and HF010, which are designed for woven sacks and film packaging rather than fibre and non-woven conversion. It also differs from injection grades like HM012T and HM065, which target moulded articles and thin-wall parts instead of spunbond or lamination lines.
Against market alternatives, HY035UR can be compared with OPaL RH38, OPaL RH25X, and IOCL fibre-oriented polypropylene grades. RH38 is typically positioned strongly for spunbond non-woven applications, while RH25X is more associated with fibre and filament uses. HY035UR stands out for buyers specifically seeking MRPL-origin material with Novolen gas phase processing characteristics, strong non-woven suitability, and product-family alignment with gas-fading resistance and compliance-oriented documentation logic.
